    摘要： This invention relates to a method of producing enhanced strength portland cements. Under the process of this invention, certain portland cements, in particular those containing at least 4% C.sub.4 AF and up to 0.2% of a strength enhancing additive comprising triisopropanolamine, exhibit a marked increase in 7 and 28 day compressive strength. The triisopropanolamine strength enhancing additive may be admixed with cement powder or may be interground as a grinding aid with cement clinker during finish milling.

    摘要： A TSV structure suitable for high speed signal transmission includes a metal strip portion that extends through a long and small diameter hole in a substrate. In one example, the metal strip portion is formed by laser ablating away portions of a metal sheath that lines a cylindrical sidewall of the hole, thereby leaving a longitudinal section of metal that is the metal strip portion. A second metal strip portion, that extends in a direction perpendicular to the hole axis, is contiguous with the metal strip portion that extends through the hole such that the two metal strip portions together form a single metal strip. Throughout its length, the single metal strip has a uniform width and thickness and therefore can have a controlled and uniform impedance. In some embodiments, multiple metal strips pass through the same TSV hole. In some embodiments, the structure is a coaxial TSV.
